3 A half cylinder of radius R and length L R is formed by cutting a cylindrical pipe made of an insulating material along a plane containing its axis The rectangular base of the half cylinder is closed by a dielectric plate of length of length L and width 2R A charge Q on the half cylinder and a charge q on the dielectric plate are uniformly sprinkled Electro static force between the plate and the half cylinder is closest to qQ 2 E RL a c qQ 28 RL qQ 48 RL b d qQ 88 RL
